In this step by step instruction video, learn how to solve the system of equations problem when there are two variables, using the methods of substitution and elimination. These are two methods, which can be utilised to derive a solution.
When two equations are given, it is an example of system of equations problem, the aim being to find the values of the variables, which work in both equations in other words, we are looking to determine the combination of numbers that works in both equations. The values of the variables also serve as the coordinates which deem the intersection point of the two equations (represented by linear lines on a graph).
For those of you who also requested a blog on solving a system of equations with three variables, that will also be done in the near future!
As usual, if you have any questions or suggestions on what you would like to learn, please feel free to contact me!
